Ron Paul was apparently saying America's foreign policy is responsible for the creation of al-Qaeda and their intent to wage violent jihad - ignoring al-Qaeda's reliance on classical Muslim teachings of Jihad to explain their intent....
Ron Paul reiterated AQ talking points that America is being targeted because:
1) Infidel presence in Saudi Arabia (a religious issue)
2) Iraqi infant mortality following the sanctions - that has turned out to be bogus and the authors of the report have retracted their numbers
3) America's support for the non-Muslim state of Israel
Besides the fact AQ was formed before points 1 & 2 and AQ tried to massacre thousands of Americans in the '93 WTC bomb attack prior to the 1995 report claiming 500,000 Iraqi children died due to UN sanctions (as opposed to even more Kurdish children dying due to Iraqi government sanctions from the 80's and 70's), the question then becomes why aren't there any non-Muslim al-Qaeda groups?
Everything on AQ's talking points list can be extrapolated to non-Muslim nations or even Muslim nations but carried out by other world powers - such as the Soviet Union's support for the regimes in Syria, Cuba and Iraq, etc.
As to American foreign policy, I think SE Asia has been far worse off than the Arab world. So, should we expect transnational Buddhist religious extremist groups appearing anytime between the last thirty-five years and now?
If that simple formula results in the creation of AQ, why has it never been reproducible?
